Application filed October 29, 1919.

T 0 all whom it may concern:

Be it known that I, NATHANIEL B. Posr, a citizen of the United States,and a resident'of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements in Pop-CornMolds, or which the following is a specification.

My invention relates to improvements in pop corn molds, and has for itsobject the provision of a simple and efiicient device of this characterby means of which pop corn balls may be formed with great ease andexpedition;

Other objects will appear hereinafter.

The inventionv consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will 'be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which Fig. 1, isan end view of. an apparatus embodying the invention,

Fig. 2, a transverse section of the same,

Fig. 3, a top plan view of the same, and

Fig. 4, a longitudinal section taken on line 4-4- of. Fig. 3'.

The preferred form of construction, as illustrated in the drawings,comprises a suitable table 5 having a mold member secured centrally tothe top thereof, said mold member being formed of a strip of sheetmetal, bent as indicated, to form a plurality of? semi-cylindrical moldrecesses 6, the ends of said strip being bent to "form flanges 7 whichare secured to the table top to hold the mold member in place. A moldboard 8 is swingingly mounted on. the table top 5, being carried by arms9 pivoted on brackets 10 secured to the table top, and said mold boardbeing provided with an operating handle 11 for convenience inmanipulating the same. Stop pins 12 are also secured to brackets 10 inposition to limit the upward swing of said moldboard for convenience inoperation. A second mold member is secured to the under side of the moldboard 8, said second mold member also consisting of a strip of sheetmetal bent to form a plurality of semi-cylindrical mold recesses 13,supplementary to the recesses 6, the ends 1% of said strip being securedto the ends of the mold board 8, as shown. The arrangement is such thatwhen the mold board 8 is swung down- Specification of Letters Patent.

wardly into operative relation with the table top, the recesses 13co-operate with the recesses 6 to form cylindrical mold chambers open.at their opposite ends, so that the pop corn material placed in andover the mold recesses 6 will be thus com pressed into cylindricalforms. A; suitable housing 15 is secured to the tabletop and arrangedabout the mold recesses 6 to retain material therein when first placedin the apparatus.

Arranged in each of the cylindrical mold chambers thus provided is apair of mold heads 16, .each provided with a spherical mold recess 17 inits inner face, the arrangement being such that when said mold heads arebrought together a ball will be formed of t-he material in thecorresponding cylindrical mold chamber, as best indicated in Fig. 2. Anoperating bar 18 extends across the ,topof the table '5 adjacent theopen ends of the cylindrical mold chambers, and all of the-mold headsl6-operating in the corresponding ends of the cylindrical mold chambersare secured to the corresponding operating bar so as to compelsimultaneous operation thereof. Operating levers 19 are pivoted at 20 tothe table 5 and project upwardly through slots 21 provided in the tabletop, the upper ends of said levers being pivoted to the correspondingoperating bars 18. The levers 19 are connected by links 22 withoppositely arranged eccentric cra k pins on the discs or plates 23secured to an operating shaft 24c mounted longitudinally in the tabletop and between the sets oi. levers 19. This operating shaft 2 1- isprovided with an. operating crank handle 25, by means of which the samemay i be oscillated when desired.

In use, the mold board 8 is first swung upwardly until the arms 9 restagainst the stop pins 12 and the mold heads 16 are withdra v11 into thepositions indicated in Fig. 1. Thereupon a proper amount of popcornmaterial is poured into and over the mold recesses '6 and the mold board8 swung'back into horizontal position, thus causing the mold recesses13, co-operating with the recesses 6', to form the pop corn materialinto substantially cylindrical bodies within the various mold chambersand between the mol'dheads 16. Thereupon the mold heads 16 are forcedtogether by operation ot the crank handle 25-, and this material furthercompressed into balls.

The mold board 8 is then swung upwardly out of the way, and the moldheads 16 separated, whereupon the balls may be readily removed. In thisway pop corn or similar material may be readily and quickly formed intoballs. The specific form and arrangement of parts disclosed is a simpleand effective one for the purpose.

WVhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having described my invention what 1 claim as new and desire to secureby Letters Patent is a 1. A mold-comprising a support; a mold memberrigidly mounted on said support and provided at one side with a moldrecess therein open at its ends; a mold board pivotally mounted on saidsupport to swing into and out of operative position with relation tosaid first mentioned mold member; a mold member secured to said mold Iends; a pair of oppositely arranged mold heads slidably mounted in saidmold chamber; and means for simultaneously forcing said mold headstoward and away from each other, substantially as described.
